GBUSHING, GRINDING, REFINING, AND MIXIIIG MACHINE.

Application filed October 2 2, 1925. Serial No. 84,205.

The present invention relates to crushing, grinding, refining and, mixing machines, and aims to provide improvements in the coacting members having a rubbing or wiping contact when crushing, grinding, refiningror mixing material between them.

he improvements maybe used in various machines, being particularly intended for use in chocolate making machines, although the improvements may be used in machines for crushing, grinding, refining and mixing various materials.

Another object of the invention is the provision vof rubbing or wiping contact means including rubbing or wiping members having rocking or oscillatory action as they move along a'surface with which they are in contact.

A further object is the provision for mounting the rubbing or 'wiping members for rocking action.

A still further object is the provision of such a device wherein the rubbing or wiping members will not wear flat, said members having rounded surfaces which will wear away to maintain the surfaces curved or rounded. 7

It is also an object of the invention to provide the improvements aforesaid using a simple, practical and eflicient construction.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as

hereinafter described'and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

- The invention is illustrated in they accompanying drawings, wherein- Figure 1 is a fra mentar side elevation of a crushing, grin ing, re ning or mixing machine embodying the improvements, portions being shown in section.

Fig. 2 is a section on the line 22 of Fig.1.

Fig. 3 is a rear edge view of the parts shown in Fig. 2.

.The improvements are illustrated as being embodied in a rotary machine comprising a cylinder or cylindrical casing 7, constituting 'the stator or stationary member, within which the rotor or rotary member is movable. However, the improvements may be used in other types of machines for which the improvements are suitable. For example, the member 7 may be flat or of other formthan as shown,lthe action of the rubbing or wiping members 8 against the member 7 being the same. However, for purpose of convenient-description, the rotary motion will be referred to, without limitation thereto.

The rubbing or wiping members 8 are of barlik'e form and are disposed transversely of their path of movement along the inner or active surface of the cylinder or member 7, said surface being of stepped formation, so as to have the steps 9 of ratchet-like form. Each member or bar 8 is provided with a pair of longitudinal ribs 10 whose surfaces are converted or rounded trans versely surfaces of the bars 8 rub or wipe along the stepped surface of the member 7, to act upon the material between the members 7 and 8 for crushing, grinding, refining or mixing the material. The steps 9 of the member 7 are formed with small grooves 11 parallel with the steps, which have been found to facilitate the action on the material as the bars or members 8 move along the steps over said grooves.

The members or bars 8 are held yieldingly under spring pressure against the member 7, to obtain the desired pressure between the members 7 and 8,'and the yielding action permits the members 8 to have rocking or oscillatory action when moving from each step 9 to the next, as will hereinafter more fully appear, in order to facilitate the grinding action as, well as to cause the members 8 to wear down along curved surfaces.

As shown, the members 8 are arranged in roups, with two sets of members 8 in eac group, and any suitable number of alined members 8 in each set' disposed end to end. Each member or bar 8 is provided at that side opposite to the ribs or rounded surfaces 10 with ears or lugs 12 through parallel with the member 8. A leaf spring 15 is provided at its free end with a sleeve 16 loosely embracing the rod 13v intermediate the ends of the member 8, and other leaf springs loosely embracing the rod 14. As shown, the spring 15 is broad, .while the springs 17 are narrow, with the springs 17 arranged adjacent the ends of the member 8, and the spring 15 between the springs 17. Thus,

thereof, and said rounded or curved which front and rear rods 13 and 14 extend 17 have sleeves 18 at their free ends each member or bar 8 has a double hinge connection with the leaf springs 15 and 17 thereof, permitting the rocking or oscillatory movement of the member 8 about the spaced axes of the rods 13 and 14. The springs 15 and 17 have their sleeves 16 and 18, respectively, located between the ears or lugs 12, thereby holding the member 8 and springs assembled.

For each group of members 8 there is provided a carrier comprising bars 20, 21 and 22 between which the leaf springs are clamped and secured, so that said springs are trailed from said bars to drag the members 8 along the member 7. The leaf springs 15 and 17 of one set of each group are longer than the springs of the other setof menibersv 8, to space the two sets of members 8 apart, and the rear members 8 of the group are of greater height than the members 8 of the front set, whereby the two sets of members may be spaced apart longitudinally of the line of movement thereof. The springs 15 and 17 of the front member 8 of each group are clamped between the bars 20 and 21, while the spring of the rear members 8 of the group are clamped between the bars 21 and 22.

As shown,.the bars 20, 21, 22 of each group of members 8 are riveted or otherwise secured together, and are carried by an arm 23. Said arms 23 are pivoted, as at 24, to a wheel or rotary member 25, to enable the arms 23 to be adjusted about the pivots 24 in order to regulate the pressure with which the springs 15 and, 17 press the members 8 against the member 7. The mounting and adjustment of the arms 23 may be the same as disclosed in the copending application of John McIntyre, Serial No. 693,686, filed February 18, 1924.- Thus, a ring 26 .is mounted for turning movement on the wheel 25, and has slots 27 engaged by pins or studs 28 carried by the arms 23, in order that the turning adjustment of the ring 26 on the wheel 25 will swing the arms 23. By

swinging the arms rearwardly the pressure of the springs 15 and 17 is relieved, whereas when the arms are swung forwardly with reference to the direction of rotation, the

' springs are flexed or bowed so as to increase I the pressure. One or more of the arms 23 may have the arms 29 with which suitable adjusting means 30 is connected, in order that the ring 26 may be adjusted on the wheel 25.

.In operation, the rubbing or wiping members S'are moved along the members 7, the motion being circular in the machine as shown, and the springs 15 and 17 press said members8 with the desired pressure against the member 7 to obtain the grinding, refining, crushing or mixing action. The small grooves 11 facilitate the action by reducing the tendency for the material to slide along,

the member 7 with the members 8, so that the members 8 will pass across the particles for crushing or grinding same. As the front rib 10 of each member 8 passes from one step 9 to the next'step, the member 8 rocks forwardly on the rear rib 10, and then as the rear rib passes to the lastnamed step, the member 8 rocks rearwardly on the front rib 10. In this way, the members 8 have rocking or oscillatory motions forwardly and rearwardly on the rear and front ribs 10, respectively, as said members move along the steps 9 of the member 7. This assists in the grinding or crushing action, as well as preventing the members 3 from wearing down fiat. To thecontrary, the ribs or curved surfaces 10 will Wear down along curved lines to-maintain the convex curvature of said ribs, and thereby maintain the advantageous grinding or crushing action that the curved ribs or surfaces 10 possess. The springs 15 and 17 enable the members 8 to rock or oscillate forwardly and rearwardly a limited amount, the springs 15 holding the front ribs 10 against the member 7, while the springs 17 hold the rear ribs 10 against said member 7. The springs 15 and 17 are yieldable, so that either the front or the rear ribs 10 may move away from the member 7 to a limited extent.

The rocking motion of the members 8 will not only increase the life thereof, but will also decrease the time necessary for accomplishing the work to be performed.
